A year ago, Google introduced Rust to the Android Open Source Project (AOSP) to improve security, stability, and quality. We needed to demonstrate that Rust interoperability with C and C++ is sufficient for practical, convenient, and safe use within Android. This analysis focuses on making C++ functions available to Rust so that new Rust code can be added while taking advantage of existing implementations in C++. We analyze how Android uses C++ and ensure that interop is convenient for the vast majority of our use cases.”]
